Adaptive cruise control (ACC)
CAUTION
Use the appropriate gap setting
in accordance with local traffic
regulations.
Cancelling ACC
Press either the brake or clutch
pedal, or switch B. The system will
return to standby mode but will retain
the set speed and gap in the
memory. The ACC indicator will go
off.
Resuming ACC
Press the RES switch. The ACC
indicator illuminates and the system
will resume with the previously set
speed and vehicle gap setting if
conditions permit.
Switching ACC off
Press switch A.
Note: Pressing switch A does not
return the system to standby mode.
The stored speed is not retained.
Note: To temporarily deactivate the
system press switch B.
Automatic deactivation
The system is dependent on various
other safety systems, for example
ABS and ESP. If any of these systems
are malfunctioning or reacting to an
emergency, the system is
automatically deactivated.
In the event of automatic deactivation
a signal will sound and the message
ACC cancel is displayed in the
information display. You must then
intervene and adapt your driving and
speed to vehicles in front.
An automatic deactivation can be
due to the:
•
vehicle speed falling below 30
km/h (20 mph)
•
wheels lose traction
•
brake temperature is high, for
example when driving on
mountainous or hilly roads
•
engine speed is too low
•
radar sensor is covered
•
parking brake or electric parking
brake (EPB) is applied.
If the engine speed drops too low, a
message is displayed in the
information display instructing you to
change down a gear (manual
transmission only). If you do not
follow this recommendation then the
system will go into automatic
deactivation mode.
Note: The system will not operate if
the electronic stability programme
(ESP) has been manually switched
off.
